It's quite difficult to know what the problem is you want to fix here.
Your initial post indicated it was the query with the OR condition
that was causing you the problems, but the plan you've posted has no
OR condition?!

You're more likely to get help here if you take time to properly
explain the situation and post the information that's actually
relevant to the problem you're having, or state the problem more
clearly, as there's a mismatch somewhere.

It might also be worth having a look at
https://wiki.postgresql.org/wiki/Slow_Query_Questions . EXPLAIN is not
going to tell us what part of the query is slow. I'll let the wiki
page guide you into what to do instead.
